## Summary description

Passive CBO SFP28 direct-attach copper cable, 0.5 meter length, designed for 25Gbps SFP28 ports. Provides a short-range, low-latency connection between compatible network devices such as switches, servers and NICs. Ideal for top-of-rack and adjacent-rack interconnects where a reliable, cost-effective passive copper link is required.

## Long description

Passive CBO SFP28 direct-attach copper cable 0.5 m for 25Gbps networks is a factory-terminated twinax cable assembly designed for short-reach, high-speed links between SFP28 ports. The 0.5 metre length provides a compact, low-latency physical connection for adjacent devices such as top-of-rack switches, servers and network interface cards, enabling reliable 25Gbps data transfer without the need for optical transceivers or separate patch panels.
Advantages
This direct-attach copper cable offers simplified deployment and predictable performance for 25Gbps links. As a passive solution it consumes no additional power for signal conversion, reduces component count and lowers cost compared with active or optical options. The short fixed length minimizes cabling clutter and helps maintain signal integrity with low latency and consistent throughput suitable for dense rack environments.
Suitable for
Top-of-rack switch to server connections in data centres
Adjacent-rack interconnects where short, high-speed links are needed
Direct links between SFP28 network interface cards and switches
High-density switch stacking and spine/leaf network segments
Key specifications
Interface type: SFP28-to-SFP28 direct-attach copper (twinax)
Data rate: up to 25 Gbps per lane
Length: 0.5 metre
Connector form factor: SFP28-compatible plug
Cable type: passive twinax copper assembly
Typical applications: short-range, rack-level interconnects
How to use
Insert each SFP28 plug into the corresponding SFP28 port on the network devices until the latch engages. Ensure both devices support passive SFP28 direct-attach copper cables and that firmware or vendor compatibility lists are checked if required. Route the 0.5 m cable to avoid sharp bends or kinks; maintain recommended bend radius and avoid mechanical strain on connectors. No external power or configuration is required for the cable itself—link speed and status are managed by the connected devices.
Usage recommendations
Use this cable for short, fixed-length connections inside racks or between adjacent racks. Verify compatibility with your switch or NIC vendor to ensure full 25Gbps operation and monitor link status after installation. Avoid exposing the cable to excessive heat or compressive forces and replace if the connector housing or cable jacket shows visible damage.
